Breath Stacking Module for Pressure Support Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no mechanism for breath stacking therapy for patients and clinicians who prefer pressure-controlled ventilation, as existing technologies only support breath stacking during volume control ventilation.
Innovation Solution
A pressure support system comprising a pressure generator, sensors, and processors that deliver a pressurized flow of breathable gas, with sensors indicating readiness for breath stacking therapy and processors controlling the pressure generator to implement a breath stacking therapy regime, mimicking breath stacking in volume control mode while returning to pressure support ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pressure control ventilation is used, then patient comfort and clinical preference are improved, but breath stacking therapy capability is lost
Solution Approach 1:
The pressure control ventilation system is enhanced with a breath stacking module that enables the system to perform both standard pressure control ventilation and breath stacking therapy. The system can switch between these modes based on clinical needs, making it universally applicable for different therapeutic requirements without requiring separate dedicated devices.
Solution Approach 2:
The system dynamically adjusts between pressure control ventilation mode and breath stacking therapy mode based on real-time sensor feedback and clinical requirements. The breath stacking module can be activated or deactivated during operation, allowing the system to adapt its functionality dynamically rather than being fixed in a single mode.
2Reliability
If volume control ventilation with breath stacking is used, then alveolar ventilation and thoracic development are improved, but ventilation mode flexibility is reduced
Solution Approach 1:
The system provides both volume control ventilation and pressure control ventilation capabilities, with breath stacking functionality available in both modes. This allows clinicians to select the most appropriate ventilation mode for each patient while still accessing breath stacking therapy benefits, thereby maintaining ventilation mode flexibility without compromising alveolar ventilation effectiveness.
3Device complexity
If pressure control ventilation is used, then system simplicity is maintained, but therapeutic effectiveness for breath stacking is reduced
Solution Approach 1:
A breath stacking module acts as an intermediary component that bridges pressure control ventilation and breath stacking therapy. This module includes sensors to detect breath stacking events and control logic to initiate appropriate pressure increases, enabling therapeutic effectiveness without requiring complete system redesign or excessive complexity.
Solution Approach 2:
The system incorporates sensors that continuously monitor respiratory parameters and provide feedback to the control system. When breath stacking events are detected, the feedback mechanism triggers the breath stacking module to adjust pressure levels accordingly, ensuring therapeutic effectiveness through real-time monitoring and automatic adjustment without manual intervention.
